MUMBAI: Starting Friday, Mumbai's neighbouring localities of Thane, Badlapur, Kalyan and certain parts of Navi Mumbai received "extremely heavy" rainfall of more than 200mm. Thane recorded 236mm rain, Kalyan 231mm and Ambernath 280mm. But it was Badlapur which bore the brunt of the intense monsoon activity with 447mm rainfall-half of what Mumbai received 14 years ago in 2005 on the same fateful day of 26/7. The torrential rain caused rivers Ulhas and Waldhuni in the vicinity to overflow, bringing life to a standstill and even marooning Kolhapur-bound Mahalaxmi Express between Badlapur and Vangani stations for 15 long hours.
In Navi Mumbai, too, Nerul, Airoli, Belapur and Vashi received over 200mm rain during the 24-hour period. Mumbai appeared relatively calm and yet Indian Meteorological Department's Santacruz observatory recorded 219mm rain-making it the second wettest day for the season after 375.2mm received between July 1 and 2.
Sridhar Balasubramanian, associate faculty, IDP Climate Studies, IIT-Bombay, said westerly winds had pushed cloud bands till Badlapur, which caused the intense downpour. "The winds were all westerly which pushed the clouds towards the Kalyan-Badlapur belt. On Friday and Saturday, the circulation was close to Mumbai which then moved towards Kalyan and Badlapur. Fortuntely for Mumbai, the winds were very strong so the clouds did not stay in the city for long. They were all pushed to the interior areas towards Thane and beyond. Yet, Santacruz got 219mm, which is extremely heavy rain," he said.
Between 8.30am and 8.30pm on Saturday, IMD's Colaba observatory recorded 36.4mm rainfall and Santacruz 18.3mm.
By Saturday afternoon, the IMD had issued a red alert warning for Mumbai, Thane, Raigad and Palghar, saying extremely heavy rains at isolated places were "very likely" over the next 48 hours.
IMD officials said strengthening of monsoon currents and formation of a low pressure area over north-west Bay of Bengal will further intensify rainfall over north Konkan, which includes Mumbai, in the next 48 hours, starting Saturday afternoon.
"We expect the rainfall activity to continue over the next two days due to the low pressure which has formed over the Bay of Bengal and is moving westward. It is expected to strengthen westerly winds. Besides, the increasing low pressure closer to parts of north Konkan, which includes Mumbai, is expected to have a larger impact," said K S Hosalikar, deputy director-general (western region), IMD.
